What's the status of the linker errors across tool chain versions seen by building the 'omap3_evm' board?
This was already discussed in the threads [1] and [2], but it seems to me that there was no acceptable fix, yet?
E.g. with CodeSourcery's tool chain 2009q1-203 I get
arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e33f] overlaps section .rel.dyn [8003f5e0 -> 80044e6f] arm-none-linux-gnueabi-ld: section .dynsym [80044e70 -> 80044f0f] overlaps section .bss [8003f5e0 -> 8007e33f] arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections
What we learned from [2] is that using [3] fixes the build (at least for me with the tool chain mentioned above). I.e. converting omap3_evm_version from u8 to int
-static u8 omap3_evm_version; +static int omap3_evm_version;
makes the issue disappear.
But if I understood the discussion correctly, this is no acceptable fix and can be used only as debug help (?).
Any further hints?
Thanks
